Unity3D在按键时移动精灵

Question

当我按下w 键时，我正试图移动一个精灵。我一直在使用我在 YouTube 上找到的教程，但我似乎无法让它发挥作用。这是代码。也许我在转换时遇到问题；我可以看到 x 位置增加，但精灵没有做任何事情。

#pragma strict

var startPoint : Vector3;
var endPoint : Vector3;
var speed : float;
private var increment : float;
var isMoving : boolean;

function Start ()
{
    startPoint = transform.position;
    endPoint = transform.position;
}

function Update ()
{
    if (increment <= 1 && isMoving == true) {
        increment += speed/100;
        Debug.Log("Moving");

    }
    else {
        isMoving = false;
        Debug.Log("Stopped");

    }

    if (isMoving == true)
        transform.position = Vector3.Lerp(startPoint, endPoint, increment);

    if (Input.GetKey("w") && isMoving == false) {
        increment = 0;
        isMoving = true;
        startPoint = transform.position;
        endPoint = new Vector3(transform.position.x, transform.position.y, transform.position.z + 1);

    }
    if (Input.GetKey("s") && isMoving == false) {
        increment = 0;
        isMoving = true;
        startPoint = transform.position;
        endPoint = new Vector3(transform.position.x, transform.position.y, transform.position.z - 1);
    }
}

试试这样的：

function Update () {

    if (Input.GetKeyDown(KeyCode.W)) {
        increment += speed / 100;
        transform.position = Vector3.Lerp(transform.position, transform.position + Vector3.forward, increment);
    }

    if (Input.GetKeyDown(KeyCode.Z)) {
        increment += speed / 100;
        transform.position = Vector3.Lerp(transform.position, transform.position + Vector3.back, increment);
    }
}

另外，检查检查器中的速度是否不为 0。如果您想连续移动，请将 Input.GetKeyDown 更改为 Input.GetKey。
